The resignation of Broxtowe MP Anna Soubry from the Conservative Party has led to calls for a by-election to be held.

In a letter to the Prime Minister, signed by three MPs, Anna Soubry said the Conservative Party "no longer reflects the values and beliefs we share with millions of people throughout the United Kingdom".

Eleven MPs have now joined the new Independent Group, including Nottingham East MP Chris Leslie, who resigned from the Labour Party on Monday.

Former Conservative, MPs Sarah Wollaston and Heidi Allen also joined Anna Soubry in resigning from the Tories on Wednesday.
